ftplistparse.h

自己改写的在WINCE上开发用的EVC++的FTP操作示例工程,希望能给相关人士提供帮助.

////////////////////////////////////////////////////////////////////////////////

// Code taken from D. J. Bernstein (C ==> C++)

// ftpparse.c, ftpparse.h: library for parsing FTP LIST responses
// 20001223
// D. J. Bernstein, [e-mail]
// http://cr.yp.to/ftpparse.html
//
// Commercial use is fine, if you let me know what programs you're using this in.
//
// Currently covered formats:
// EPLF.
// UNIX ls, with or without gid.
// Microsoft FTP Service.
// Windows NT FTP Server.
// VMS.
// WFTPD.
// NetPresenz (Mac).
// NetWare.
// MSDOS.
//
// Definitely not covered: 
// Long VMS filenames, with information split across two lines.
// NCSA Telnet FTP server. Has LIST = NLST (and bad NLST for directories).
